Abstract
A magnetostrictive application probe is disclosed wherein the probe includes a preassembled sensor element mounted as an application housing installation as an installable unit. The modular nature allows interchanging with various electronic assemblies, and may be an explosion proof installation.
Claims11
A probe comprising:
- a magnetostrictive sensor adapted for detecting and measuring the level of liquid in a container and provide corresponding signal processing signals;
- a signal conditioner having a buffer circuit configured to condition the signal processing signals to a buffered signal;
- a housing enclosing said signal conditioner and having an exterior and interior, the housing isolating the magnetostrictive sensor from signal processing circuitry exterior of the housing;
- first means for mounting said signal conditioner and at least a portion of the sensor in said interior of said housing;
- and
- a second means for permitting the buffered signal from the signal conditioner to be sent to the signal processing circuitry exterior to said housing.
